'ro ALL WHOM IMMAY eoNcneN':

Be itkno'wnthat I, LEWi-S-DIE-TEM'CH, of the town of Sandwiclnin the county oflDe Kalb, and State'of Illinois, have invented certain'ncw and useful Improvements Brick-Presses', and I do hereby declare that the following is a' full, clear, and exact description ofthe saine, reference'being had to the accompanying drawings making a part of this-specification, in Which-'J i i l Figure 1 isafrontelevation.

Like letters refer to the same parts in all of thgegure's. v

The natureV andobj'cct of my. invention eonsistin constructing a machine forV maliingpressed-or gravel brick by hand or by power;-

so'applyingthe-power that a'numb'er of brick can be made 'at asingl'e 'operation of the machine; in so arranging the operative parts' that ajprincipal portion of the frame can-be made of wood, in making .the vertical barl or guide S slotted' sufficiently toV receive the movable parts; andin the several combinations-hereinafter set forth and claimed. v Y

To 'enable others skilled in the art to make and use my' machine, I will describe its construction and operation. "i l Y lheframe A is made of wood,and is about four feet high, three feet long, andA one anda half foot wide, and of timbers suiciently strong tomake the machine permanent and durable. 'lothc top of'this -Wooden frame I attach orplace an iron-frame or box, B V, which is divided into as many compartments or `moulds as 4may be desired, by the partition-plates'Vund-W, 5. This cast frame is secured together by the strong bolts or rods U', and fastened to the Wooden frame A by therods U and lanches X. In .making gravel or sand brick, large'sizes arc usually made, but it is frequently desirable to make'smaller sizes, or even clay brick,` in'the -same machine. In' order to dothis,`I makemy moulds originally of the largest size desired, and then make linings or false moulds, G, which are fitted to the external on;es,.-and made o'f the size desired .for the smaller brick. These linings are made, as shoivn at fig. '3, in two sections, with recessese'and projections fitting into them, so that the parts cannot be displaced. They' are held in place bythe bolts or screivsc, fig. 1. Some changes -in the followers or plateus are also necessary, and vvill be hereinafter set forth.-

On each side of the machine I attach avertical guide-bar, S, tothe castdronframe, and to .the baseof the wooden frame.. On the inside'oi' each of these bars I make a slot, as shown at iig. T, the entire length of -the bar, or so far as may be necessary -to enable me to 'cake out the beam H and rock-shaft J Without taking the machine apart'at-its fastenings. Into the slots or grooves of the bars S, I insert, near the moulds, a beam or cross-bar, Hfby proper tongues or tenons. To the under side of thisbeam I hinge or otherwise attach the pendants I, so that their upper ends will 4rest `strongly against the beam. The lower ends of these pendants are rounded ofi' at g', and 'made broad, and to the `side a gea-ring, t, is'attached. Immediately beneath these, vstandards M are hinged or otherwise attached to th'e base of frame vA, and rest upon it. The upper ends of these standards are made broad, and are rounded off ats-y', and have. a gearing, @'at the side, like the pendants I. .Between th'e'se, I and M, I insert on place a roel:sha {`t, J, the endslof whichv are insertedvinthe grooves ofthe' guide-bars S, and near each end I attachfthe double cams 'K or eccentrics, Which have gearings or cogs, I,von r their sides, corresponding to 7L and t', and by means of which the pendants I and staudardsl'M arekept in -place and made to operate, but the power is applied bythe cam or eccentric, K. At the middle Iiattach the operating- 1ever O. This lever, and the cogs L audi, with the weight of the machine, will prevent displacement of the parts when in use.v A A l In order to take these operative parts 4out, of the machine, piace a leverancier the rock-'shaft J, and elevate f it slightly, when .the standards M will turn` downen the side. By'dropping one end of J, it also comes out,

which releases-beamH, which can, with the pendants I, also be taken ont by depressing one end; and by draw-v ing out levers P, the platen or follower will come out, so that the inachirie can be taken apart forrepairs or adjustment without loosening a single bolt or stay by reason of--the long groove in the guide-'bars S. i

The followers, figs. 1 and 5, are made in pairs, and as many pairs can be attached as desired by simply adding other short bars, Z, and increasing the Width of the machine. Each pair has a horizontal bar, D, which rests its entire len'gth on-'hea-m H. To this-are attached upright's, E, and on the top of each one of these uprights is a platen or follower, F, fitted to the mould'or die. Theuplights E are of snicie'nt length to carry the platens F to-the top of B, andare so adjusted with the covers C that when the power is applied, the pressed bricks will lie of the required' dimensions,v and when .bricks of a les's `site are to be made, tb`e pairs of followers will be taken out, as. described, and those with smaller platens' and longer uprights will be putin in place of` the large ones.` These have to be changed for each size, or Athe 'proportions oi' the brick would ngtfbe preserved' except by more' expensive changes in the machinery for applying the ponen Each end of the bar D basa tenen, d,- the outer ones fitting the groove of the guide-bar-S, 'and the inner `ones fitting similar grooves in the block Z.

Ina press to be operated by hand, there is not suiiicient movement to elevate the bricks when pressed out of 'the machine. To obviate this diiiiculty, I'attach a cross-bar, y, to the bar Dand to this cross-bar, at each end, the swinging bars or arms R. These arms or bars are connected at their lower ends with the prongs ofy thel levers 11g-which levers are pivoted to the frame at T. By depressing the levers P, the flloivers are separated from the beam H and elevated'to the top, so that the bricks can be taken olf. The covers C areitted into the iron frame by tongues I) andgrooves a, iig. 1,'and slide eitherfway. By this mode ofattaching them, they not only act as upper platens when the power isV applied, but, when being slid into position, will catand pish oil any excess of material. In order to facilitate feeding, I provide detachable hoppers, fig. 2, which are made with a sliding bottom, 7c, and divided into compartments or divisions, Z, corresponding ,t'o the nnmberof bricks to be made by each follower. I usually make the side-pieces m of iron,'and line the bottom cwith sheet iron to prevent rapid wear. i

In operation, the sand, gravel, or clay is first suitably prepared, when the hopper, fig. 2, is filled. The cover C isithen shoved back and the hopper placed on the machine over the moulds., The'bottom, 7c, is then drawn out, and the material alreadymeasured olf falls into the mould. (It is desirable to have'several hoppers.) The cover C is then drawn or pushed to its place, which cuts' off all extra material. The lever O is then depressed, which elevates the beam H and the followers, and gives the brick the'required pressure.- The pressure is .then s'foniewhat relaxed, when the cover can be removed 'sutiiciently to allow the .brick to pass, when the'levers P are depressed and th@ brickl forced to the top of the machine, when they are taken Y by a pair of tongs, such as shown at iig. 6, or otherwise, and carried away, making, in the machine shown, Your bricks at each operation, while in other hand-machines which1I have known-itwasonly possible to make one at each operation. By

i placing a stop or catch for the lever O at its lowest position, tivo men can opercte this machine successfully,

although a greater number can Work advantageously.

Having thus fully described my invention and machine,'wl1at I claim as new, and desire to secure by- Letters Patent, is-- Y 1. The followers, composed ofthe parts D,E,; and F, in combination with thebeam H, guides Z and S, and

lever P, substantially as specified.

2. The arrangement of the bar D/oeam H, pendants I, and rock-shaft J, with the single slotted or grooved bars S, so that the operating parts can all be readily removed, substantially asl herein described.

. 3. The combination andl arrangement of the 'lever O, rock-shaft d, provided with the eccentrics K3 the removable standards M, and pendants I, guide-hars S, and followers D E`F with frame A B, 4all consti-noted and operating substantially as specified. v I
